This has become a "right of passage" in our home for 6th graders. My oldest daughter used the textbook, audio CD (for pronunciation of words like Mitochondria), and the Notebook. She learned so much, that when she was at the Orthopedic Doctor, and he told her what she had injured, she explained to him the bones, muscles, and ligaments involved!
Then my son was in 6th grade, and ready to use this curriculum. I knew he would not like the notebook--it's just not his thing. So I found a mom who has lists of vocabulary words and tests. He did not use the CD, but did very well reading it himself and typing the vocab, then taking the test. He finished it in only four months because he liked it so much!
This, to me, is the gold standard for elementary or middle school Anatomy!
